I'm using this seatpost on my Cannondale System Six road bike and I cannot complain. I previously had a ControlTech 2A Team Issue seatpost, and the difference is significant; lighter, compliant and surely smooths out the chatter to a bare minimum. The small, 10mm setback,slight aero shape and rugged construction really makes this seatpost worthy for MTB also.

I traded up from Ritchey WCS and Easton EC-90 seatposts and this one has the feel of a Thomson Masterpiece....at the same weight.
